I started school in 1965 as a 'rising 5', i.e. I went to school for the summer term before I was 5. I had already learnt the alphabet and could spell a few words before that, but we were taught ITA.
It really confused me, my mum & dad had no idea what it was and couldn’t help, and, more importantly, I had to sit on my left hand and use my right as the former was the "devil's hand"
It was even more confusing when in year 2 we went back to 'proper' English and it was treated like the previous 18 months hadn't existed.
I really struggled with letter - order, my writing was labelled 'illegible' and had to use squared paper to help me write out words.
skwl - school, only it wasn't a 'w' but a strange double 'oo' looped together.
